OK. After a little more digging in MySQL''s manual on SubSelects, I''ve changed the finder_sql entry in my model declaration: class District < ActiveRecord::Base has_many :interviewers, :order => "lname, fname" has_many :applicants has_many :unassigned_applicants, :class_name => "Applicant", :finder_sql => "select a.* from

I am using the the authorization recipe outlined in Rails Recipes.Is it possible for one role, say ''admin'', to have access to every action on every controller without explicitly having to create a Right for each? I know this will not work as is, and to force it to do so would violate MVC, but is there some other way to accomplish having something like this in a controller:

I have a Person model. Person has_many lab_urls. The LabUrl model has a title and a url, which are both required. Now, I want to update a LabUrl object and stick some invalid data in there. And I want the person that has that invalid LabUrl to now be invalid, too. That doesn''t seem like too much to ask for. How can I do that? Right now, this is happening: >> me = Person.find(1)

Hi, my name is Patrick Edwards, and I'm currently a CS major at Kent State University. I have always been interested in doing work with compilers and LLVM seems to be a perfect fit for me to learn more over the summer, and also contribute to open-source projects at the same time.

Hi there, I am trying to fit a generalised linear model to some loan application and default data. The purpose of this is to eventually work out the probability an applicant will default. However, R seems to crash or die when I run "glm" on anything greater than a 5-way saturated model for my data. My first question: is the best way to fit a generalised linear model in R to fit the

I am looking for someone to continue the Ogg Traffic tradition. Ogg Traffic is a weekly update and status report about what's happening with Ogg development as well as other related projects and interesting bits of news (Xiph, Speex, Icecast, etc.). Stan Seibert, who resurrected OT recently, is busy with Real Life activities that prevent him from writing an OT (http://www.vorbis.com/ot/)

I would like to impute missing data in a set of correlated variables (columns of a matrix). It looks like transcan() from Hmisc is roughly what I want. It says, "transcan automatically transforms continuous and categorical variables to have maximum correlation with the best linear combination of the other variables." And, "By default, transcan imputes NAs with "best

I have a standard form built with rails, which a user to my site can use to submit data. Unfortunately one user just managed to submit exactly the the same data three times in a row. From the server logs it seems as though he didn''t use his back button and then resubmit everything. It looks more like he got a bit fed up waiting for the form to process and pressed the submit button three
